Check if you need planning permission
To find out if you need planning permission for your proposal use the Planning Portal's interactive house.
To use the interactive house, hover over the area of the house that you are seeking to develop. Then click on the highlighted area for more information about if you need planning permission.
The Planning Portal also provides information on permitted development rights. This allows you to make certain types of minor changes to your house without needing to apply for planning permission.
You can find out the necessary information on the Planning Portal's permitted development rights page.
Before you submit a householder planning application form, view our validation checklists page. This provides the necessary scaled plans and supporting information required.
